HOOK.

To all 'whom t may conce/Mt.'

Be it known that I, SAMUEL P. JoHNson, a citizen of the United States, residing at Fithclsville, in-the county of Pickens and State of Alabama, have invented certain new and useful Improvements in Hooks, of which the following is a speciiicatibn, reference being had to the accompanying drawings.

This invention relates to certain improvements in hooks and it is an object of the invention to provide a novel and improved device of this general character especially designed and adapted for use in connecting a hook in ,a trace chain or the like to a singletree.

It is also an object of the invention to provide a device ofthis general character providing novel and improved means whereby the trace chain or the likecan be readily disconnected from the hook and particularly in the event the trace chain is taut as when vtangled up with the draft animal.

Another object of the invention is to yprovide a novel and improved device of this general character comprising a body member and a latch carried thereby the opposed faces of the body and latch havingregister- .ing openings to provide an opening` to receive a trace chain ring together with means for normally maintaining said latch and body in such relative arrangement.

The invention consist in the details of construction and in the combination and arrangement of the several parts cf my improved hook whereby certain important advantages are attainedk andthe device. rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

vIn order that my invention may bel Vthe better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure l is a view in top plan of a hook constructed in accordance with a preferred embodiment of my invention;

Figure 2 is a view in side elevation of the hook as herein disclosed;

Figure 3 is a view in top plan of the body of the hook with a portion broken away and the spring applied, the latch being removed;

Figure 4C is a vertical sectienal view taken through a device as illustrated lin Figure l with the portionof the pivot member of the latch in elevation; and

Figure 5 is a view in bottom planv of the latch as herein set forth.

As disclosed in the accompanying drawings, B denotes kthe body ofy my improved hook provided at one endl portion with an opening l and through which is adapt-ed to be directed a trace ring of a conyentional type for connecting lthe body to a singletree. .Y i i Y Y The opposite end portion ofthe. body B is reduced from above in thickness to lprovide an extension 2, therupper face fof whichV being substantiallyY flat. The` opposite or lower face of the extension 2-is flush. with the adjacent facey of they body B and the thickness of the extension` 2Uas herein disclosed is equal to substantially one-half of the thickness ofthe body Bv proper.

` The inner or upper surface ofthe extension 2 adjacent its outer or freey end is provided thereacross with arecess having the walls thereof opposed in a Vdirection lengthwise of the bodyB rounded, with the outbows of said rounded portionsopposed as is clearly illustrated in Figure Sfof the accompanying drawings.. 1

The wall `5 provided in the body B ab'ove the extension 2 has at vits centralportion la substantially semi-circular recess 6 which is in continuationof a portion of the wall of the opening. 7 disposedA throughr both the body Bproper and the extension 2thereof. The lower portion of the wall 5 immediately adjacent the face 3 of thelbody B isfundercut to provide a recess 8 open at its opposite end.

L denotes a latch member` which when in closed position overlies,y the extensi0l112 in close contact with the. face 3t thereof. The latch L has its lower or inn'erfaceprovided with an outstandingpivot memberQor shank 9', said shank or memberfpartially extending beyond the adjacent` or `Linner end of the extension 2 and which extended portion is snugly received within the4 recess 6. The rea-rwall 10 of the latch Lto one side of the memberonshank 9y issubstantially perpendicular to thefr longitudinal axis of 4 the latch L While ltheiwall 11 at 'the opposite side of the member or shank 9 is arranged slightly inwardly of the wall 10 and disposed on an outward Vlli angle` of.A rapproximately thirty degrees. When the portion 10 of the rear wall of the latch L'is in contact with the adjacent portion of the shoulder 5 the movement of the latch L is limited in one direction with said latch L overlying the extension 2 of the body B. The arrangement of the wall 11 permits the latch L to haveflimited swinging movement relative to the body B and to an extent to permit the desired engage- 'ment'or disengagement of a trace ring beto receive portions of thev coiled spring-15 encircling the member or shank 9, portions of said spring being also received in the recess 8V hereinbefore referred to. @ne eX- treinity of the spring 15 is angularly disposed as at 16 for contact with the portion 11 of the rear wall of the latch L, while the opposite end portion of the spring 15 is provided witli an angular extension 17 for contact with they adjacent portion of lthewall 5. The spring 15 constantlyT urges thejlatch L intov a position with the extension 2 and to maintain said latch in such position.

lIn order that the latch L may have its full extent of swinging movement I find of advantage to have the extension 17 of the spring 15 seat within a recess 18 produced in the portion 11 of the latch L.

l/Vith a hook constructed in accordance with an embodiment of my invention a trace ring or the like may be readily arranged with the'openings afforded by the recesses d and 12 upon proper swinging movement of the latch L and said ring will normally be effectively held between said extension 2 and latch L.' f Y Y When it is desired to release the trace Aring itA is only necessary to swing the latch L into an open position and thismovemeiit of the latch can be accomplished vpartially irrespective ofthe strain imposed upon the trace such as being unduly taut when the trace is tangled up with a draft animal.

The member or shank 9 is of a lengthY to extendlbeyondthe body B and disposed through said extended'portion is acotter lpin 19' or the'like which serves to maintain .thelatch L in applied position with respect :tothe body B51 Y tible of some change and modification without departing` from the principles and spirit thereof and for this reason l do not wish to be understood as limiting myself to the pre cise arrangement and formation of the several partsherein shown in carrying out my invention in practice except as hereinafter claimed.

I claim:

1. A. hook of the class described, a body reduced in thickness to provide an extension,

said body and extension at thefjunction thereof being provided with an opening, a latch normally overlying the'eiitens'ion and provided withan integral pivot member eX- v tending through the opening, the end wall of the latch at one side ofthe pivot member Y serving as a stop to limit movement Yof the latch member in one direction, the portion of the end wall of the latch member at opposite sides of the pivot member being on an angle to permit the latch member to have limited outward swinging movement, and.

means for constantly urging'the latch in the first direction andto maintain the latch in aposition to overlie the extension, the opposite faces of the latch and extension being provided thereacross with recesses nor-V mally registering to provide an opening.

2. A hook of the class described comprising a body having an extension at one end of a 'thickness less than the thickness of the body, the body to one side of the extension having an end wall provided with a recess, a latch normally overlying the extension, a laterally directed pivot member carried by the inner end of the latch and extending be yond said end, said extended portion of the pivot member being seated within the recess at the inner end wall of the body, and a spring member encircling the pivot member and coacting with theopposed end walls of the latch and body for normally maintaiiiing the latch in aV position overlying thefextension of the body, opposed faces of the latch and body being provided ywith recesses normally in register to providey an opening, the portions of the walls of the latch and the body adjacent, the spring being recessed to receive portions of the spring.

In testimony whereof l hereunto afixmy i signature.
